| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The security notion of conventional ramp key distribution scheme (KDS) is that fraudulent centers and users can get partial information on any key that leak in stages according to the number of fraudulent users. In this paper, we define a new ramp KDS, show lower bounds on the memory size of entities for a new ramp KDS, and describe the concrete construction that meets corresponding lower bounds. The security notion of a new ramp KDS is that fraudulent centers and users can get partial information on any key that leak in stages according to the number of fraudulent centers and users. | |
